Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Deserialization of untrusted data (CVE-ID: CVE-2025-55182)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data passed to React Server Function endpoints. A remote non-authenticated attacker can send a specially crafted HTTP request to the React server components and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Information disclosure (CVE-ID: CVE-2025-55183)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the server may expose the source code of any server function when receiving a specially crafted HTTP request. A remote attacker can gain access to sensitive information.
The vulnerability affects the following components:
- react-server-dom-webpack (Meta)
- react-server-dom-turbopack (Meta)
- react-server-dom-parcel (Meta)
Successful exploitation requires the existence of a Server Function which explicitly or implicitly exposes a stringified argument.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2025-55184)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can send a specially crafted HTTP request, which can cause an infinite loop and prevent future HTTP requests from being served, leading to a denial of service condition.
The vulnerability affects the following components:
- react-server-dom-webpack (Meta)
- react-server-dom-turbopack (Meta)
- react-server-dom-parcel (Meta)
4) Deserialization of Untrusted Data (CVE-ID: CVE-2025-67779)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can send a specially crafted HTTP request, which can cause an infinite loop and prevent future HTTP requests from being served, leading to a denial of service condition.
The vulnerability affects the following components:
- react-server-dom-webpack (Meta)
- react-server-dom-turbopack (Meta)
- react-server-dom-parcel (Meta)
